1 KISSsys Instruction: KISSsys Instruction: Using and Manipulating the Table of Variants Using and Manipulating the Table of Variants 1 Introduction It can be of interest to use one KISSsys model for the calculation of many gearboxes of the same type (variants). Gearbox series can be therefore easily been used with only one model. It is then very easy to calculate all the variants of this gearbox and get data for a product catalogue. KISSsoft AG has developed a template for that purpose. The template is a table in order to have a certain overview over the variants data. The table contains the variable names of the parameterized values and the values of every variant. It is possible with functions to add columns/whole variants, to switch between variants, or to delete unwanted variants ins table-of-variants.doc 1 / 6

2 2 Handling of the Table The table has to be copied from the templates called 302-TableOfVariants.ks and then entered into the tree structure of a finished gearbox model. In order to handle the table the user should know what functions are in it, and what they do. The functions are listed in the next chapter. Function Name DeleteData Dialog GetData Read_File SetData Write_File Functionality Deletes selected data set form the table of variants Asks for the number of columns. Every defined column must contain data Takes a selected variant and distributes it values to the target variables Reads a *.csv file which can contain a table of variants written in excel and translates it into KISSsys. Data field separator needs to be semicolon (;) Sets the current values of the model to a new variant in the table of variants Writes the table into a *.csv file 2.1 Defining the Number of Parameters In order to open the table the first time, right click on the symbol in the tree structure and choose the function Dialog. A dialog asking for the number of columns appears. Please enter here the number of your parameters +1. For Example: If you have two bearings with positions changing from one variant to the other, you have to enter 2 into the field Columns. OK opens the table. Figure Definition of two variables The table shows 3 columns. The first row shows what information is contained in the following rows. Per default there are no layouts defined. In the first place only name Layout is defined in the table and no other information. First we should define the variables we want to parameterize in the variants. As already mentioned this would be the position of two bearings. The whole path to the variable needs to be defined assuring that functionality will work in every case. 2 / 6

into the cells in the first row and typing in the definition starting from the top level or root (_O). In the example following lines are used In top cell of column 2: _O.GB.Shaft1.Bear1.

3 Figure The bearings used as example In order to define the position of the two bearings as parameters for the different variants fill in the name of the variables into the first row by simply clicking into the cells in the first row and typing in the definition starting from the top level or root (_O). In the example following lines are used In top cell of column 2: _O.GB.Shaft1.Bear1.position In top cell of column 3: _O.GB.Shaft3.Bear2.position Figure Definition of the variables 2.2 Setting Data as a Variant The variable names for the parameters are now defined. The values for the current variant have now to be defined. The function SetData goes through the column and looks for the variables written in the first row of the column. It takes the values of these variables in the model and puts them into the correct column of the layout row. 3 / 6

This opens a dialog, where the name of the variant can be entered.

The function will add a line with the entered name as layout title, when entering a new name.

variant with different values change the position of the bearings in the model and execute SetData. Call the new set Test2.

You can vary KISSsoft files of a calculation directly from KISSsys.

4 Figure Position of the two bearings to be set as data for the variant "Test1" Right click on the table icon and choose the function SetData. This opens a dialog, where the name of the variant can be entered. A name which is already existent means that the variant will be overwritten. The function will add a line with the entered name as layout title, when entering a new name. Figure Setting data from a current model to the variant "Test1" (proceed from left to right) and table of variants In order to create a new variant with different values change the position of the bearings in the model and execute SetData. Call the new set Test2. Figure Table with 2 variants If a variant with the selected name already exist in the table and you want to overwrite it a question of this will be asked see picture Figure Setting a KISSsoft File as a Parameter It is also possible to vary the KISSsoft file of a calculation using the TableOfVariants. You can vary KISSsoft files of a calculation directly from KISSsys. If you have already defined data in the module, but it is not saved as file yet, please do that first, to save the data. Then right click on the calculation symbol in the tree structure and choose Dialog. In the dialog, verify that the options Save automatically or Ask for Saving are activated. Then run the function SetFlags and change the list entry from Save in KISSsys to Save in KISSsoft. This function saves the calculation data for the first time as a file. These two options guarantee that your calculation file is independently from the KISSsys model saved in a KISSsys file. 4 / 6

4 Getting Data from a Variant The function GetData can also be called by right click on the table icon.

The function then goes through the model and enters variant specific parameters into the variable values of the model.

5 Delete a Variant Whenever a variant has to be deleted, the user can call the function DeleteData by right click on the table and click on the function.

5 Figure Setting the Saving Mode of Calculations Figure Setting flags Then you enter the variable filename in a new column of the TableOfVariants and proceed the same way as with other variables. 2.4 Getting Data from a Variant The function GetData can also be called by right click on the table icon. A dialog is opened with a list containing all the variants of the table. One of these variants can be chosen and OK has to be clicked. The function then goes through the model and enters variant specific parameters into the variable values of the model. This function makes sure, that the values arrive in the whole model automatically. Figure Choose the desired variant from the list 2.5 Delete a Variant Whenever a variant has to be deleted, the user can call the function DeleteData by right click on the table and click on the function. The function calls a dialog with a list where the user can choose the variant to delete. With Ok the chosen variant will be deleted. 2.6 Write_File This function will write the whole table of variants as *.csv file to let user to modify entities manually e.g. in Excel. Using function with right mouse click open a dialog to select name for the file. The default filename DB_DATA.csv is shown. It is possible to change this name. The file will be always saved as.csv type. 5 / 6

Figure 2.6-1 Write table information in *.csv - file The file is located to the project folder.

7 Read_File It is also possible to read in a file which contains the variants data.

6 Figure Write table information in *.csv - file The file is located to the project folder. It is easy to add now lines and information in the table and then save the file again. Figure Data can be easily modified e.g. with Excel 2.7 Read_File It is also possible to read in a file which contains the variants data. Select function Read_File form the table and select a file to read in. All data is automatically set in the table and existing data is overwritten. Table is then shown with this new information.
